[pianotech] pin torque??

[Don Mannino]

Jack,

Usually it is measured in Inch Pounds, sometimes in Newton Meters.
For the purposes of reporting to a problem to a manufacturer, you should measure with the string on, counter-clockwise (lowering pitch).
For the purpose of measuring for consistency when doing test drilling, of course you would measure in either direction without any string.

  I got myself a new toy, a vibrating digital torque wrench "Snap-on" for testing pin torque, but I have a few questions.
  When people talk about the measuring pin torque is it in foot pounds or inch pounds?
  Also do you measure with the string on or off? And lastly is the measurements for clockwise or counterclockwise?

  Thanks,
  Jack Houweling
